将数据库值分配给 Python 变量

Question

Making a simple script which grabs the latest value from the database and sends over HTTP GET to a destination

however when I use "mycursor.fetchone()" I get returned the value ""(Decimal('21.00'),)"

Am I missing something? I'd like to just extract a raw value

Code snippet:

mycursor.execute("SELECT RAINFALL FROM WATHER_MEASUREMENT")
rainfall = mycursor.fetchone()

#create a URL variable 
 URL='https://*****'
 PARAMS = "temp={temperature}&pressure={pressure}&rh={humidity}&precip={rainfall}".format(**vars())

requests.get(url = URL, params = PARAMS)

Answer 1

fetchone returns dict not value

add this after second line:

rainfall = rainfall['RAINFALL']
